FIG. 1 is a drawing illustrating the concept of a universal integrated circuit card (UICC) included in a terminal according to an exemplary embodiment.

According to an exemplary embodiment, a first terminal 100 may be implemented as a cellular phone, a smartphone, a tablet personal computer (PC), or the like. It should not be interpreted as limiting a technical scope of the inventive concept by the form of the terminal 100.

Referring to FIG. 1, a smart card, for example, a UICC 10 may be loaded into the first terminal 100. For example, the UICC 10 may be loaded into the first terminal 100 in the form of a chip or card.

In the specification, the smart card may refer to the concept including a secure element (SE), such as a subscriber identity module (SIM), a universal subscriber identity module (USIM), and a UICC, which may manage a subscriber identification information set.

The UICC 10 may store personal information of a user and operator information regarding a mobile network operator (MNO) to which he or she subscribes. For example, the UICC 10 may store and manage a plurality of subscriber identification information sets.

Each of the plurality of subscriber identification information sets may widely mean a data set including data for identifying a subscriber, a UICC (or USIM), or an MNO. Each of the plurality of subscriber identification information sets may correspond to one phone number. According to an exemplary embodiment, each of the plurality of subscriber identification information sets may include an integrated circuit card identifier (ICCID), an international mobile subscriber identity (IMSI), a mobile station international ISDN number (MSISDN), key information for network access, and the like.

FIG. 2 is a block diagram illustrating a process of managing a subscriber identification information set in a UICC of FIG. 1. FIG. 3 is a drawing illustrating a file structure of a UICC file system of FIG. 2. FIG. 4 is a flowchart illustrating a method for providing a multi-number service according an exemplary embodiment.

Referring to FIGS. 1 and 2, there may be a UICC file system 12 in the UICC 10. A subscriber identification information set managing application 14 and a USIM application 16 may be installed in the UICC 10.

In the specification, an application may be used as the meaning of including application software and may refer to the concept of including an applet.

The subscriber identification information set managing application 14 may register a subscriber identification set (e.g., a first subscriber identification information set set1) to be used when the first terminal 100 accesses a network in the UICC file system 12.

Referring to FIGS. 2 and 3, a file structure of the UICC file system 12 may be configured with several files in a lower level of a master file (MF) 12A. An EF-DIR 12B which is a linear fixed type of an element file (EF) as a mandatory file included in the several files may be present as a lower level file of the MF 12A.

The ADF-USIM 12C may be the highest node of EFs (e.g., an EF-ICCID 12E, an EF-IMSI 12F, an EF-MSISDN 12G an EF-KI 12H, and the like) used by the USIM application 16. Link information about the ADF-USIM 12C may be included in the EF-DIR 12B.

Several files may exist in a lower level of the ADF-USIM 12C. EFs, that is, the EF-ICCID 12E, the EF-IMSI 12F, the EF-MSISDN 12G the EF-KI 12H, and the like, necessary for actually accessing a mobile communication network may be configured in a lower level of a dedicated file 12D as a mandatory file included in the several files. Upon actually accessing the mobile communication network, the EF-ICCID 12E, the EF-IMSI 12F, the EF-MSISDN 12G and the EF-KI 12H may be read to the outside of the UICC 10 by the USIM application 16.

In the UICC 10 according to an exemplary embodiment, the EFs, that is, the EF-ICCID 12E, the EF-IMSI 12F, the EF-MSISDN 12G and the EF-KI 12H, necessary for actually accessing the mobile communication network may be updated through the subscriber identification information set managing application 14 or the USIM application 16 (see reference denotation “update 1” or “update 2”).

For example, an ICCID1 included in the first subscriber identification information set set1 may be stored in an EF (e.g., the EF-ICCID 12E) for storing an ICCID of the UICC file system 12. An IMSI1 included in the first subscriber identification information set set1 may be stored in an EF (e.g., the EF-IMSI 12F) for storing an IMSI of the UICC file system 12. An MSISDN1 included in the first subscriber identification information set set1 may be stored in an EF (e.g., the EF-MSISDN 12G) for storing an MSISDN of the UICC file system 12. KI1 for network access may be stored in an EF (e.g., the EF-KI 12H) for storing a key.

When the first terminal 100 performs network authentication, a subscriber identification information set stored in the UICC file system 12 may be transmitted to the outside through the USIM application 16.

The subscriber identification information set managing application 14 may store and manage the plurality of subscriber identification information sets set1, set2, and the like stored in the UICC 10.

The plurality of subscriber identification information sets set1, set2, and the like may be respectively stored in a memory allocated to the subscriber identification information set managing application 14.

Each of the plurality of subscriber identification information sets set1, set2, and the like may include an ICCID, an IMSI, an MSISDN, KI, and the like. For example, the first subscriber identification information set set1 may include the ICCID1, the IMSI1, the MSISDN1, and the KI1, and the second subscriber identification information set set2 may include the ICCID2, the IMSI2, the MSISDN2, and the KI2.

Referring to FIGS. 2 and 4, in operation S10, the subscriber identification information set managing application 14 may select one of the plurality of subscriber identification information sets set1, set2, and the like based on an external command CMD received from the outside of the UICC 10. In operation S11, the subscriber identification information set managing application 14 may activate the selected subscriber identification information set.

The external command CMD may be generated by an application executed in the outside of the UICC 10. Embodiments of the present invention are not limited thereto.

For example, the subscriber identification information set managing application 14 may activate the first subscriber identification information set set1 by selecting the first subscriber identification information set set1 among the plurality of subscriber identification information sets set1, set2, and the like and updating the selected first subscriber identification information set set1 to the UICC file system 12.

According to an exemplary embodiment, the subscriber identification information set managing application 14 may directly update the selected subscriber identification information set (e.g., the first subscriber identification information set set1) to the UICC file system 12 via an application program interface (API) (not shown) (see reference denotation “update 1”).

According to another embodiment, the subscriber identification information set managing application 14 may update the subscriber identification information set (e.g., the first subscriber identification information set set1) to the UICC file system 12 via the API (not shown) and the USIM application 16 (see reference denotation “update 2”).

The USIM application 16 may be driven to perform various functions necessary for network access and subscriber authentication of the first terminal 100.

Upon network access and subscriber authentication, the USIM application 16 may transmit a subscriber identification information set stored in the UICC file system 12 to the outside of the UICC 10.

According to an exemplary embodiment, the USIM application 16 may relay an update operation (see reference denotation “update 2”) performed between the subscriber identification information set managing application 14 and the UICC file system 12.

According to an exemplary embodiment, the first terminal 100 may manage an address book, incoming and outgoing text records, or incoming and outgoing call records for each subscriber identification information set. The first terminal 100 may activate an address book, incoming and outgoing text message records, or incoming and outgoing call records corresponding to an activated subscriber identification information set, based on the activated subscriber identification information set. Particularly, when a user makes a call to a telephone number included in an address book corresponding to a specific subscriber identification information set, the first terminal 100 may transmit a command CMD for activating a subscriber identification information set corresponding to the address book to the UICC 10.

According to another embodiment, the first terminal 100 may manage an application group displayed on a background screen for each subscriber identification information set. In this case, the first terminal 100 may display an application group corresponding to an activated subscriber identification information set, on the background screen based on the activated subscriber identification information set.

According to another embodiment, the first terminal 100 may provide an information protection service for each subscriber identification information set. For example, an address book, incoming and outgoing text message records, or incoming and outgoing call records corresponding to at least one subscriber identification information set requested for information protection among the plurality of subscriber identification information sets may be stored in the UICC 10 or the first terminal 100 or in a server independent of the first terminal 100. In this case, the address book, the incoming and outgoing text records, or the incoming and outgoing call records may be encrypted and stored. For example, the encryption may be performed using an encryption key in the UICC 10.

According to another embodiment, the first terminal 100 may manage content (e.g., a photo file, a voice file, a video file, and the like) for each subscriber identification information set. In this case, the first terminal 100 may be configured to verify only content corresponding to an activated subscriber identification information set, based on the activated subscriber identification information set.

According to another embodiment, the first terminal 100 may provide a secret phone service for each subscriber identification information set. In this case, when a specific subscriber identification information set receives text message or call, the first terminal 100 may fail to display the received text message or call and may store and manage information about the received text message or call in the UICC 10. Also, the first terminal 100 may transmit a text message or a voice message for providing notification of a situation where it is difficult to be in contact with a caller of the text message or call currently.

According to another embodiment, the first terminal 100 may set an authority for use an application for each subscriber identification information set. In this case, when specific subscriber identification information is activated, the first terminal 100 may refrain from using a specific application (e.g., a game application and the like). Also, the authority for use an application for each subscriber identification information set of the first terminal 100 may be set by an external terminal (e.g., a terminal of a security manager of a company).

According to another embodiment, the first terminal 100 may manage an accredited certificate for each subscriber identification information set. In this case, the first terminal 100 may be configured to use an accredited certificate, corresponding to an activated subscriber identification information set, as a default accredited certificate based on the activated subscriber identification information set.

In FIGS. 1 and 2, the UICC 10 is illustrated as an example of an IC card (or a chip card or a smart card) which stores and manages subscriber identification information sets of the first terminal 100. However, the UICC 10 may be replaced with a different name or type of card.

FIG. 5 is a flowchart illustrating a method for providing a multi-number service according another embodiment.

Referring to FIGS. 1 to 5, when the first terminal 100 is powered on in operation S20, in operation S22, the UICC 10 may perform a reset operation based on control of the first terminal 100.

In operation S24, the UICC 10 may be initialized and may register a toolkit for providing a multi-number service according to an exemplary embodiment of the present invention, based on a terminal profile of the first terminal 100. In operation S24, the UICC 10 may select the MF 12A for network access.

In operation S26, the UICC 10 may determine whether operation S24 is successfully performed. When operation S24 is not successfully performed, in operation S28, the UICC 10 may determine whether this situation is repeated a specific number of times or more.

When the situation is repeated the specific number of times or more, in operation S30, the UICC 10 may block access to the UICC file system 12.

When the situation is not repeated the specific number of times or more, the UICC 10 may perform the operation from operation S22.

When operation S24 is successfully performed, in operation S32, the UICC 10 may select and read the EF-DIR 12B.

In operation S34, the UICC 10 may determine whether operation S32 is successfully performed. When operation S32 is not successfully performed, the UICC 10 may perform the operation from operation S28. When operation S32 is successfully performed, in operation S36, the UICC 10 may access the ADF-USIM 12C based on link information of the EF-DIR 12B.

In operation S38, the UICC 10 may determine whether operation S36 is successively performed. When operation S36 is not successively performed (“No” in operation S38), the UICC 10 may perform the operation from operation S28. When operation S36 is successively performed (“Yes” in operation S38), in operation S40, the UICC 10 may read EFs (e.g., the EF-ICCID 12E, the EF-IMSI 12F, the EF-MSISDN 12G the EF-KI 12H, and the like) constituting the DF 12D located in the lower level of the ADF-USIM 12C.

After operation S40, in operation S42, the UICC 10 may be switched to an idle state. Until operation S44 is performed, the first terminal 100 may access a network by the EFs (e.g., the EF-ICCID 12E, the EF-IMSI 12F, the EF-MSISDN 12G the EF-KI 12H, and the like) read in operation S40.

In operation S44, a subscriber identification information set may be selected by a process performed interior or exterior of the UICC 10. For example, one (e.g., a first subscriber identification information set set1) of a plurality of subscriber identification information sets (e.g., first and second subscriber identification information sets set1 and set2, and the like) may be selected by an external command CMD input to the subscriber identification information set managing application 14 of FIG. 2.

In this case, in operation S46, the selected subscriber identification information set (e.g., the first subscriber identification information set set1) may be activated. In other words, each of data (e.g., the ICCID1, the IMSI1, the MSISDN1, and the KI1) of the selected subscriber identification information set (e.g., the first subscriber identification information set set1) may be updated to each of the EFs (e.g., the EF-ICCID 12E, the EF-IMSI 12F, the EF-MSISDN 12G and the EF-KI 12H) of the UICC file system 12 through various update paths (e.g., update 1 and update 2).

In operation S48, the UICC 10 may determine whether a change of a subscriber identification information set is successively performed. When the change of the subscriber identification information set is successively performed, the UICC 10 may perform the operation again from operation S24. When the change of the subscriber identification information set is not successively performed, the UICC 10 may be switched to the idle state in operation S42.

FIG. 6 is a sequence diagram illustrating a data flow of a method for providing a multi-number service according another embodiment.

A management server 200 may be a server which may manage a plurality of subscriber identification information sets stored in a first terminal 100 or register the plurality of subscriber identification information set through network authentication. According to an exemplary embodiment, the management server 200 may be, but is not limited to, an MNO server.

According to an exemplary embodiment, the management server 200 may map and store identification information of the first terminal 100 with a plurality of subscriber identification information sets corresponding to the identification information.

Referring to FIGS. 1 to 6, in operation S50, the first terminal 100 may transmit a request to add or delete a subscriber identification information set based on an input of its user to the management server 200.

FIG. 12 is a drawing illustrating an example of an activation pattern input via a user interface (UI) of a terminal shown in FIG. 1. FIG. 13 is a drawing illustrating a UI according to an exemplary embodiment for receiving an identification number of a user after an activation pattern of FIG. 12 is input. FIG. 14 is a flowchart illustrating a method for providing a multi-number service according another embodiment.

Referring to FIGS. 1, 2, 12, and 14, a terminal 100 may include a display 110 for displaying a UI for receiving an external input from its user.

The display 110 may display a UI for receiving an activation pattern (e.g., a first activation pattern PT1) of the user to select and activate one of a plurality of subscriber identification information sets (e.g., first and second subscriber identification information sets set1 and set2, and the like).

According to an exemplary embodiment, the display 110 may display a plurality of pattern units PUs, each of which is implemented in the form of a dot.

As shown in FIG. 12, in operation S150, the user may input the first activation pattern PT1 which connects some of the plurality of pattern units PUs.

Referring to FIG. 13, after the first activation pattern PT1 is input, the display 110 may display a UI for receiving an identification number of the user.

According to an exemplary embodiment, the identification number may be a personal identification number (PIN).

In operation S152, the user may enter his or her identification number using a UI displayed on the display 110 of FIG. 13.

In operation S154, the terminal 100 may determine whether the identification input entered in operation S152 is an identification number corresponding to the first activation pattern PT1 input in operation S150, that is, whether a correct identification number is input.

For example, the terminal 100 may store a corresponding identification number for each specific activation pattern and may determine whether the entered identification number is identical to the stored identification number.

When the correct identification number is not entered, the terminal 100 may receive an activation pattern of the user again in operation S150.

When the correct identification number is entered, in operation S156, the terminal 100 may activate a subscriber identification information set corresponding to the input activation pattern.

FIG. 15 is a drawing illustrating another example of an activation pattern input via a UI of a terminal shown in FIG. 1.

Referring to FIGS. 12 to 15, a user may register a second activation pattern PT2 different from a first activation pattern PT1 in advance.

According to an exemplary embodiment, the terminal 100 may be configured to activate a first subscriber identification information set set1 when the first activation pattern PT1 is input thereto and activate a second subscriber identification information set set2 when the second activation pattern PT2 is input thereto.

In FIGS. 12 and 15, for convenience of description, an exemplary embodiment is exemplified as a plurality of pattern units PUs implemented in the form of a dot. However, various modifications are possible in the form of implementing the plurality of pattern units PUs. For example, the plurality of pattern units PUs may be implemented in a three-dimensional (3D) form.

According to an exemplary embodiment, an activation pattern (e.g., the first activation pattern PT1 or the second activation pattern PT2) input by the user may be a form of a voice pattern of the user. In this case, different subscriber identification information sets may be activated based on a voice pattern input by the user. The voice pattern may be input by a voice recognition module (e.g., a microphone) implemented in the terminal 100. For example, when the voice “apple” is input, the first subscriber identification information set set1 may be activated. When the voice “tomato” is input, the second subscriber identification information set set2 may be activated.

According to another embodiment, an activation pattern (e.g., the first activation pattern PT1 or the second activation pattern PT2) input by the user may be a form of a bio-information pattern of the user, for example, a fingerprint pattern of the user. In this case, different subscriber identification information sets may be activated based on a fingerprint pattern input by the user. The fingerprint pattern may be input by a fingerprint recognition module (not shown) implemented in the terminal 100. For example, when a fingerprint pattern of a first user is input, the first subscriber identification information set set1 may be activated. When a fingerprint pattern of a second user is input, the second subscriber identification information set set2 may be activated. In other words, several persons may activate their subscriber identification information sets using their unique information, thus receiving a service not to invade their privacy while sharing the one terminal 100. The bio-information pattern may be modified in various forms such as an iris pattern other than the fingerprint pattern.

FIG. 16 is a flowchart illustrating a method for providing a multi-number service according another embodiment.

Referring to FIGS. 1, 2, and 16, in operation S160, a user may store a corresponding terminal state for each of a plurality of subscriber identification information sets (e.g., first and second subscriber identification information sets set1 and set2 and the like) stored in a memory allocated to the subscriber identification information set managing application 14 of the terminal 100.

According to an exemplary embodiment, the terminal state may be a communication establishment state of the terminal 100. For example, the communication establishment state may include at least one of whether a data network is connected, whether wireless-fidelity (Wi-Fi) is connected, whether a global positioning system (GPS) is connected, whether near field communication (NFC) is connected, and whether Bluetooth is connected.

For example, the user may use the first subscriber identification information set set1 in a home where the Wi-Fi is available to him or her. The user may use the second subscriber identification information set set2 in the outside where the Wi-Fi is unavailable to him or her. In this case, if the first subscriber identification information set set1 is activated, the Wi-Fi is connected and the data network is blocked. Also, if the second subscriber identification information set set2 is activated, the Wi-Fi is blocked and the data network is connected.

According to another embodiment, the terminal state may be a notification mode setting state of the terminal 100. For example, the notification mode setting state may be an alarm mode, a ring mode, a vibrate mode, or a silent mode.

The vibrate mode may refer to a mode of providing notification that an event occurs through vibration, and a manner mode may correspond to the vibration mode.

The silent mode may refer to a mode of preventing notification that an event occurs from being provided to the outside although the event occurs. An airplane mode or the like may correspond to the silent mode.

For example, the user may use the first subscriber identification information set set1 at his or her company. The user may use the second subscriber identification information set set2 at the other places. In this case, if the first subscriber identification information set set1 is activated, the terminal 100 may set to the vibration mode. Also, if the second subscriber identification information set set2 is activated, the terminal 100 may be set to the ring mode.

According to an exemplary embodiment, the terminal state may be an initial screen setting state of the terminal 100. For example, the initial screen setting state may include at least one of a list and arrangement of at least one application icon displayed on an initial screen, a background image of the initial screen, and whether a lock of the initial screen is set.

For example, the user may use the first subscriber identification information set set1 at his or her company and may use the second subscriber identification information set set2 at the other places. The terminal 100 may be configured to display an icon of a text editing application frequently used at the company on the initial screen when the first subscriber identification information set set1 is activated. Also, the terminal 100 may be configured to display an icon of a game application frequently used at a home of the user on the initial screen when the second subscriber identification information set set2 is activated.
